GLASS-DRAWING APPARATUS.

Specification of Letters Patent.

Patented May 8, 1217.

Application filed September 24, 1915. Serial No. 52,483.

To all whom it may concern:

Be it known that 1, CHARLES DAY, a citizen of the United States, residing at Okmulgee, in the county of Okmulgee and State of Oklahoma, have invented new and use ful improvements in Glass-Drawing Apparatus, of which the following is a specification.

This invention relates to improvements in apparatus for drawing glass, and particularly to means for elevating or drawing out the glass cylinder during the process of forming the same from the supply of molten glass, and for handling the formed cylinder to lower and dispose it within a receiving rack preliminary to the subsequent severing and flattening operation.

The primary object of the invention is to provide simple, reliable and eilicient hoisting means for operating the drawing tool and drawing the cylinder and for lowering the cylinder after formation within a receiving rack or receptacle, in such manner as to enable all of these operations to be, if

desired, performed by a single workman,

2'. 6., the drawer or operator in direct charge of the drawing mechanism.

A further object of the invention is to provide a drawing mechanism whereby the several operations set forth may be carried out and controlled in such a way as to reduce time, labor and expense and the number of employees required to perform the work.

The invention consists of the features of construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawings in which Figure l is a view in elevation of a drawing mechanism embodying my invention, showing the parts in the position'they appear at the beginning of the draw.

Fig. 2 is a View of a portion of the drawing mechanism shown in Fig. 1 as the parts appear when the draw is completed and the cylinder elevated.

Fig. 3 is a view of the remainder of the drawing mechanism showing the parts as they appear in the handling of the glass cylinder, the latter appearing in full and dotted lines in partially and fully lowered positions, respectively.

Referring to the drawings, 1 designates the usual drawing tool, supported by a vertically-movable draw-carriage 2, and provided with the usual bait 3 whereby the cylinder i is drawn from a body of molten glass 5 disposed within a dog house, fur-- nace or other molten glass receptacle 6. The draw-carriage 2 is provided with wheels or rollers to travel upon a vertical track rail 7 arranged in axial alinement with the re ceptacle 6, said carriage being movable upwardly along said track rail in the drawing operation, as will be readily understood. In practice, the operation of drawing the glass cylinder is ordinarily performed by one operator, while one or more attendants or operators are additionally required to detach the cylinder and handle it to dispose it within areceiving rack or upon a suitable support ready for the severing and flattening steps of treatment in the production of window or like sheet glass. This practice of employing additional operators or at tendants to handle the glass cylinder after it is formed and prior to the operation of severing it is a source of considerable expense in a large glass plant, and it is the purpose of my invention to provide means whereby all of the operations named may be performed by a single operator, 2'. 0., the one performing the drawing operation without material extra effort on his part so that such expense may be saved.

In accordance with my invention, I provide an upper track rail 8 which is disposed in an inclined plane and connects at its higher end with the rail 7. The carriage 2 is adapted to travel from the rail 7 onto the rail 8 and back again, and arranged for travel solely on the rail 8 is a second or cylinder lowering carriage 9 provided with wheels or rollers to run upon said rail 8. Normally, as at the beginning of a drawing operation, the carriage 9 is arranged at the upper end of the rail 8 and overhanging the rail 7 and said carriage is provided with a guide pulley or sheave 10 for the guidance of a hoisting cable or draw cable 11 extending over said pulley and in parallel relation with the respective rails 7 and 8 and connected at one end with the carriage 2 and at its opposite end with a hoisting drum or Windlass 12.

It will be understood that in the operation of drawingthe cylinder the carriage 2 is moved upwardly to hoist the drawing tool and cylinder through the medium of the cable 1.1 which is moved in a hoisting direction by the operation of the drum 12. During the movement oi. the carriage 2 from its lowermost position until it passes onto the upper end of the rail 8 the carriage 9 re mains stationary and is held in a stationary position by means of a controlling and retracting cable 13 fixed at one end to said carriage 9 and connected at its opposite end with a drum or Windlass 1 1, said drum or Windlass being locked against movement in an unwinding direction to maintain the carriage 9 in the stated position during the upward travel of the carriage 2.

When the carriage 2 passes to the upper end of the rail 7 and therefrom onto the rail 8 the drum 14L is released for unwinding motion, and as the drum 12 continues to wind up the cable 11 the carriage 2 will engage and transmit motion to the carriage 9, pushing the latter before it down the inclined rail 8. In this operation the cylinder is suspended from the carriage 2 and as the carriages 9 and 2 move downwardly along the rail 8 the lower end of the cylinder l which is detached from the body of glass 5 abuts against one end of a horizontally extending rack or receptacle 15 and is thus held from horizontal motion, while the upper end of the glass cylinder is carried forward with the carriage 2 and cable 11 until both carriages 2 and 9 pass from the position shown in Fig. 2 to the liar end of the track 8, as shown in Fig. 3, whereupon the cylinder will be held in the partly lowered or inclined position shown in Fig. 2. The cable 11 is then released for unwinding motion from the drum 12 and allowed to descend so as to lower the glass cylinder gently and easy into the receptacle 15, after which the neck of the cylinder is detached from the bait, and the carriages returned to normal position by operating the drum 1 1 to wind up the cable 13 and unwind the cable 11, the motion of the carriage 5) being arrested when it resumes its normal position, while the carriage 2 is allowed to descend along thetraek 7 and controlled in its descent by the drum 12, whereby the parts of the apparatus will be arranged for a repetition of the drawing and cylinder racking operations.

In practice the drums are controlled by governing devices arranged so to be manipulated by the attendant or operator making the draw, who need only perform the simple operations oil adjusting certain controlling levers or handles by which the drums are governed, allowing the entire work of drawing the cylinder and depositing it in its rack prior to severing and flattening to be carried out by a single operator, thus dispensing with (he use of other operators and saving the additional expense. The drums may be controlled by air, hydraulic, steam or electrical means, as may be deemed most desirable. By the use of hoisting mechanism of the character described the operator will be relieved of the necessity of directly handling these cylinders and hence will not be required to perform any material additional amount of work.
